{"version":"1.0","type":"rich","title":"Fork of Example","description":"A collapsible D3 tree diagram visualizes the hierarchical relationships within a dataset on hip replacement rankings, organized by country, city, institution, and expert. The visualization uses a tidy tree layout calculated with `d3.tree()` and rendered with SVG paths. Data is loaded asynchronously from a CSV file via `d3.csv`, then processed into a nested tree structure. The hierarchy is built with `d3.hierarchy()`, and nodes use `d3.linkHorizontal()` for curved connecting links, with animations for collapsing and expanding branches.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f51f484179ee46b9ad01cc4e926aa855?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
